How To Edit Java Policy File?

Question

I am having a problem using netbeans in which im trying to start the Java DB. Its giving me an access denied error. After some research i have found this Unable to start derby database from Netbeans 7.4 which provides a fix. I attempted to edit the java policy file but I am unable to open the java.policy file because I am unsure how. I have also found this, which says how to open the poicy file http://docs.oracle.com/javase/tutorial/security/tour2/wstep1.html but when I enter policy tool at command line, nothing pops up.

This is the error i keep recieving

I'm on a Mac (running OSX Mavericks, JDK 1.7 update 51, and Glassfish 4.0) and I had the same problem being unable to edit the file. So I did the following:

1. Find your java.policy file in /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/jre/lib/security/
2. start VIM by typing sudo vim java.policy
3. Go into file insert mode by typing the Vim command a
4. add the following code to your permissions: // permission for Glassfish 4.0 deployment permission java.net.SocketPermission "localhost:1527", "listen";
5. go back to the command mode by pressing the Esc button.
6. Now save and quit the file by typing :wq
7. Restart the server and you should be okay
